EN-EL18 battery the same one used in the D4, for D800??

For your application you need something you can leave and walk away from for 12 hours at a time, right?

If you have the Nikon MB-D12 grip ($310) what about using the Nikon BL-5 Battery Chamber Cover? The description says it's a battery chamber cover that fits the MB-D12 Battery Pack and uses a Nikon EN-EL18 rechargeable lithium ion battery and is compatible with the D800/D800E. Actually it is the complete battery tray and cover for holding the battery.

The EN-EL18 battery is the same one that is used in the D4. The EN-EL18 is a 10 volt, 2000 mAh battery. The standard battery for the D800 is the EN-EL15, 7.0 Volt, 1900 mAh battery that sells for $46. How is a 10V battery compatible with a camera that uses a 7V battery?

The battery costs $125 and the only charger is a Nikon dual charger for $310. Even though it may work, this item does not seem to be a huge advantage for the price. Better to have a couple of spare EN-EL15 batteries for the standard tray, IMO.
